| A newly designed spacer to help improve attenuation without the need for a double cup design, thus increasing the space inside the cup for greater comfort and wearability |
| Attenuation: Helmet Attachment: SNR=32dB, H=34dB, M=30dB, L=24dB |
| High attenuation from a single cup design |
| Light-weight and slim compared with similarly attenuating products |
| Simple colour coding: red indicating high attenuation |
